3.3V/5V power supply module for micro:bit

Since the micro-bit development board does not have a 5V power output pin, the USB-connected 5v voltage will automatically step down to 3.3V.

When the micro-bit needs to use a 5V power supply sensor module (such as ultrasonic, servo), it needs to use a micro-bit external power module to provide a 5V power output.
